Corsair XMS Xpert RAM

Next, we continued testing with SiSoftware's SANDRA, the System ANalyzer, Diagnostic and Reporting Assistant, but we manually set the memory timings on the Corsair TWINXP1024-3200XL modules to 2-2-2-5 (CAS Latency = 2T, RAS to CAS Delay (tRCD) = 2T, Row Precharge (tRP) = 2T, Active to Precharge Delay (tRAS) = 5T). Then we raised our system's HTT clock until it was no longer stable.  Our goal was to find the maximum stable clock speed that the XPert modules could attain, without issue.  For the sake of comparison, we did the same with our reference Kingston and Corsair Pro modules as well. (Note: The Kingston modules were run at 2.5-3-3-8 timings) For all of our overclocking tests, we cranked the memory voltage up to 2.9v via the system BIOS.

Performance Comparison with SiSoft SANDRA 2005
Raw Bandwidth

 

With the memory timings still set at 2-2-2-5, we were able to hit a maximum stable clock speed of 220MHz (DDR440) with the Corsair XMS Xpert memory kit. This speed matched what the Corsair Pro modules could do at the same timings. The extra 20MHz equated to roughly a .5GB/s increase in available bandwidth in both the Integer and Floating Point portions of SANDRA's memory benchmark.

Marco's interest in computing and technology dates all the way back to his early childhood. Even before being exposed to the Commodore P.E.T. and later the Commodore 64 in the early ‘80s, he was interested in electricity and electronics, and he still has the modded AFX cars and shop-worn soldering irons to prove it. Once he got his hands on his own Commodore 64, however, computing became Marco's passion. Throughout his academic and professional lives, Marco has worked with virtually every major platform from the TRS-80 and Amiga, to today's high end, multi-core servers. Over the years, he has worked in many fields related to technology and computing, including system design, assembly and sales, professional quality assurance testing, and technical writing. In addition to being the Managing Editor here at HotHardware for close to 15 years, Marco is also a freelance writer whose work has been published in a number of PC and technology related print publications and he is a regular fixture on HotHardware’s own Two and a Half Geeks webcast. - Contact: marco(at)hothardware(dot)com
